My suspicion is with the brass causing a reaction on the tube. Fittings are made from brass but they usually have a thick nickel plate on them. I'm currently running a small test with clear tube running my loop a few times a day (rig under contruction). Its been about a week and its holding ok

Considering most radiators are only made, really, by a couple of manufacturers, it's very likely we are all using (essentially) the same basic radiators with the same innards. If the brass being used has any copper as part of the alloy, that could explain the green toilet water that Omen showed up top and what clouding of the tubes. And also why copper sulfate solutions make the clouding even worse!

+ Rep so hard for you Omen!!! :

So the question is, who is using what radiators? I have a feeling XSPC and Swiftech are going to be high up there. I have two Swiftech QP's of my own, a 320 and 120.

Problem is we need an additive to prevent the issue from occurring . Or something has to be done.I mentioned no brands because i know for a fact i tested 3 brands and others had same problems with other brands. So this testing was totally non biased.

Only thing i proved is the tubing manufacturers are not to blame. At least not for the white tubing issue.nor can the blame be put on 1 company. solution would seem a chemical that could prevent it from happening . But like i said before i was just real life testing and eliminating things. Chemist i am not unfortunately. But i do have access to send stuff to a lab for testing.

I think I can safely speak for the rest in saying we really do appreciate all the work you have done!

What's interesting though is that only recently in the last year or so have we really started seeing this problem. It begs the question what has changed?

Very true i used the clear many times before.Only withing the Last year the problem accrued. Its still not solved but i have all new test equipment coming and i am going to try something.If it workd then you guys can be really happy

But lets not count our chickens before they hatch .Lol

At least we have it narrowed down so we can work on the problem now.

I agree with wermad and want to try nad test th all brass fittings.Anyone running aluminum rads? Wonder if they could duplicate it.

Know whats really going to bite.I really enjoyed the testing and don't want to stop .Besides the part where my hands are killing me from changing tubing so many times.They cramp after doing compressions a thousand times.Lol

Also have another 100 feet of tubing coming to play with also so i will destroy all of it if needed
